Amazon.com description: Product Description: Developed by Alexander Dennis in 2005 as an all-encompassing replacement for the Dennis Trident and its two bodies, the Plaxton President and Alexander ALX400, the integral Enviro400, immediately sold in large numbers, not least to London operators, which in the next eight years bought over 1,500 of them. Late in the production run, the hybrid E40H was introduced and also made good headway in London, funded largely by environmental grants. Nearly 300 of these are in service in London.

Valid to May 2015, this book finishes by introducing the MMC, the all-new development of the Enviro400 unveiled in 2014 and exemplified in London so far by two batches for Abellio and Metroline.
